Adding a uiview that contions some uibuttons not works correctly iphone monotouch

I'm using this codes to add 3 UIButtons in a UIView and then add them to my screen.

UIView  buttonsContainerView = new UIView (new Rectangle (0,0,(int) this.View .Frame .Width ,40));
            UIButton  b;
            for(int i=0;i<3;i++){
                b= new RltTabBarButton ();
                b.ImageEdgeInsets = new UIEdgeInsets (5,5,5,100);
                if(i==0){
                    b.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
                    b.TitleLabel .Text = "Details";
                    b.Frame = new RectangleF (0,350,108,40);
                    b.Enabled =true ;
                }else if(i==1){
                    b.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
                    b.TitleLabel .Text = "Map";
                    b.Frame = new RectangleF (110,350,100,40);
                    b.Enabled =true ;
                }else if(i==2){


                    b.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
                    b.TitleLabel .Text = "Agent";
                    b.Frame = new RectangleF (212,350,108,40);
                    b.Enabled =true ;
                }
                buttonsContainerView .AddSubview (b);

            }
this.View .AddSubview (buttonsContainerView );

When I run my application. Buttons added in their correct place. but they do not include any Text on their TitleLable. While I set this Item. Also they look like some images so that i can not click on them and interact with them.

I set their Enabled field true but not any changes.

EDIT: According to answers I changed my code to this:

UIView  buttonsContainerView = new UIView (new Rectangle (0,0,(int) this.View .Frame .Width ,40));

            UIButton  DetailsButton= new UIButton (UIButtonType.RoundedRect  );
            DetailsButton.ImageEdgeInsets = new UIEdgeInsets (5,5,5,100);
            DetailsButton.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                  UIControlState.Normal );
            DetailsButton.SetTitle ("Details",UIControlState.Normal );
            DetailsButton.Frame = new RectangleF (0,350,108,40);
            buttonsContainerView .AddSubview (DetailsButton);

            UIButton  MapButton= new UIButton (UIButtonType.RoundedRect );
            MapButton.ImageEdgeInsets = new UIEdgeInsets (5,5,5,100);
            MapButton.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
            MapButton.SetTitle ("Map",UIControlState.Normal );
            MapButton.Frame = new RectangleF (110,350,100,40);
            buttonsContainerView .AddSubview (MapButton);

            UIButton  AgentButton= new UIButton (UIButtonType.RoundedRect  );
            AgentButton.SetBackgroundImage (UIImage .FromFile ("ProjectRes/Images/Placeholder.png"),
                                          UIControlState.Normal );
            AgentButton.SetTitle ("Agent",UIControlState.Normal );
            AgentButton.Frame = new RectangleF (212,350,108,40);
            buttonsContainerView .AddSubview (AgentButton);

            this.View .AddSubview (buttonsContainerView );

But not any changes. we do not able to click on buttons. Their look like images. I believe that it is related to buttonsContainerView and maybe its EnableInputClicksWhenVisible. When I debug the app this view, debugger have some exeption when wants to execute its value. I was able to copy just head of this:

MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.  Name: NSInvalidArgumentException Reason: -[UIView enableInputClicksWh…

I'm not sure how to fix it.

I got it. The problem is that I set the hieght of buttonsContainerView( The view that contains buttons ) 40. but is set the Height position of buttons 350. When button's frame is outside the frame of its parent view it wouldn't respond to your touches.

You need to use SetTitle(); function of the UIButton in order to make it work. Otherwise, the TitleLabel won't be set.

button.SetTitle("MyTitle",UIControlState.Normal);

This should probably be a comment, but I cannot comment yet. I find your implementation odd and I tend to think it would cause ARC to misbehave (I assume ARC since you do not have any release code). Why not just create 3 UIButtons instead of this loop and then add all of those to your UIView?
